Description

Technical Field

[0001] The invention relates to a bearing assembly having a shaft, a housing part and a bearing, and a reducer having the bearing assembly. Background Art

[0002] As is known, shims are used to compensate for tolerances arising from manufacturing.

[0003] As the closest prior art, a method for producing a reduction gear is known from DE 10 2021 003 240 A1.

[0004] DE 1 298 545 A discloses an electromechanical analog-digital converter having a planetary gear arranged between code disks.

[0005] A rotary piston engine is known from EP 3 960 984 A1.

[0006] A reduction gear having a housing is known from DE 10 2021 004 971 A1. Summary of the invention

[0007] It is therefore an object of the present invention to improve a reduction gear in which, during operation of the reduction gear, tolerances resulting from production are compensated stably and a long service life is achieved.

[0008] This object is achieved according to the invention by a bearing arrangement according to the features specified in claim 1 and by a reduction gear according to the features specified in claim 15 .

[0009] In a bearing assembly having a shaft, a housing part and a bearing, an important feature of the invention is that a first bearing ring of the bearing, in particular an outer ring, is received in a bore of the housing part.

[0010] The second bearing ring of the bearing, in particular the inner ring, is mounted on the shaft.

[0011] wherein the shim pack axially limits the first bearing ring or the second bearing ring, in particular the inner ring or the outer ring,

[0012] The gasket set comprises a first retaining ring and one or more adjusting gaskets.

[0013] Therein, the first retaining ring is locked in a rotationally fixed manner or in a form-fitting manner in the circumferential direction.

[0014] The advantage here is that the shim pack remains stable even in the case of changes, in particular fluctuations, of the transverse forces and thus achieves axial limiting of the bearing in the desired manner. In addition, the retaining ring bridges interruptions in the contact surface, in particular, for example, grooves that extend through the contact surface. The adjusting shims are designed to be very thin and, in the case of interruptions in the contact surface, cannot permanently fulfill their intended function of axial spacing or even fail. However, since the retaining ring protectively accommodates the adjusting shims and thus the adjusting shims rest on the retaining ring without interruption, the service life of the adjusting shims is extended and can be described as fatigue-resistant in particular. This prevents the adjusting shims from entering grooves that interrupt the contact surface of the adjusting shims, since these grooves, i.e., interruptions in the contact surface, are bridged by the retaining ring.

[0015] In particular, the anti-rotation locking prevents the disk package from moving when the transverse forces fluctuate, and thus a long service life can be achieved.

[0016] In particular, the axial direction is always parallel to the direction of the axis of rotation of the shaft, wherein in particular the circumferential direction and the radial direction are based on the axis of rotation of the shaft.

[0017] In an advantageous embodiment, the first retaining ring is locked in a circumferential direction so as to be rotationally fixed or form-locked.

[0018] The method is as follows: an axially continuous hole is formed in the corresponding retaining ring, and the hole is especially arranged radially outside the adjusting washer.

[0019] wherein the connecting element, in particular a pin, in particular a slotted pin, passes through the hole.

[0020] The connecting element extends into the axial hole.

[0021] In particular, the axial bore is formed in a centering collar of the cover or in a shaft shoulder,

[0022] In particular, the hole is radially spaced from the adjusting shim.

[0023] In particular, the holes are spaced apart from each other in particular uniformly in the circumferential direction and / or are arranged at the same radial distance. The advantage here is that a simple anti-rotation locking is achieved and a long service life is achieved thereby, because an outward or inward shift is prevented, in particular under lateral force load fluctuations.

[0024] In an advantageous embodiment, the first retaining ring is locked in a circumferential direction so as to be rotationally fixed or form-locked.

[0025] This is achieved by, in addition or alternatively, at least the first retaining ring, in particular on its radial outer circumference, having at least one radially oriented projection which projects into a corresponding, in particular radially oriented recess, in particular a groove, in particular an axial groove, of the housing part.

[0026] Particularly wherein, the area covered by the radially oriented recess in the axial direction comprises the area covered by the shim pack in the axial direction. Advantageously, anti-rotation locking can be achieved with very low complexity, i.e. by shaping the retaining ring and the first axial groove in the housing part.

[0027] However, in an embodiment of the disk assembly in which the first and second retaining rings are identical in structure, a further axial groove is provided in the housing part, which has an angular spacing from the first axial groove that corresponds to the rotation angle of the bayonet connection.

[0028] In an advantageous design, adhesive is arranged in or on the shim pack, in particular for the anti-rotation locking of the shim pack and / or the adjusting shim. Advantageously, the anti-rotation locking can be realized in a simple and cost-effective manner.

[0029] In an advantageous embodiment, the first retaining ring has a greater axial wall thickness, in particular a greater thickness, than each of the adjusting washers. This has the advantage that the washers have a higher rigidity than the respective individual adjusting washers. As a result, the adjusting washers are arranged in a protected manner and the washers can even be supported on abutment surfaces that have interruptions in the circumferential direction. The interruptions are produced, for example, by grooves that are bridged by the washers.

[0030] In an advantageous embodiment, the disk package has a second retaining ring, which is connected to the first retaining ring in a locking manner, in particular by means of a bayonet connection.

[0031] In particular, the second retaining ring has a greater axial wall thickness, in particular a greater thickness, than each of the adjusting washers,

[0032] Particularly wherein, the adjusting shim is arranged axially between two retaining rings. Advantage is here that a fast and easy-to-establish connection can be used to protectively accommodate the adjusting shim in the shim pack.

[0033] In an advantageous embodiment, the first retaining ring is designed to be identical in structure to the second retaining ring, in particular to be completely identical. This has the advantage that only a few additional components are required, namely in particular only one retaining ring. The shim set can be produced by rotating one of the two previously parallel-aligned retaining rings by 180° and receiving the adjusting shims, and depending on the number of adjusting shims received, the shim set has a different number of adjusting shims and a corresponding axial width.

[0034] In an advantageous embodiment, the radial range covered by the respective retaining ring includes the radial range covered by the adjusting shim. This has the advantage that the adjusting shim can be arranged inside the shim pack and thus surrounded by the retaining ring in a protected manner. In addition, radial outward displacement of the adjusting shim can be prevented by the axially protruding elastic region.

[0035] In an advantageous embodiment, each of the retaining rings has, at its radially inner edge region, an axially protruding elastic region, in particular a tongue-shaped elastic region, extending in particular in the circumferential direction.

[0036] In particular, the elastic region is connected at its respective end located at the front or at the rear in the circumferential direction to the remaining respective retaining region,

[0037] wherein the elastic regions of the first retaining ring are spaced apart from one another in the circumferential direction,

[0038] wherein the elastic regions of the second retaining ring are spaced apart from one another in the circumferential direction,

[0039] wherein the elastic region of the first retaining ring axially engages the elastic region of the second retaining ring,

[0040] In particular, the respective elastic region of the first retaining ring protrudes in the axial direction and has a projection region protruding opposite to the axial direction, and / or the respective elastic region of the second retaining ring protrudes opposite to the axial direction and has a projection region protruding in the axial direction,

[0041] In particular, the elastic regions are arranged at the same radial distance and / or are spaced uniformly from one another in the circumferential direction. This has the advantage that two retaining rings can be connected to one another by means of their elastic regions and thus a shim set can be formed including the shims. In this way, the shims are connected in a protected manner by the two retaining rings connected to one another. The contact surface of the respective shims on the respective retaining rings is designed to be uninterrupted in the circumferential direction and thus prevents failure of the respective shims.

[0042] In an advantageous design, the elastic region is arranged radially inside the radial range covered by the adjusting washer. This has the advantage that an outward displacement or radial movement of the adjusting washer is prevented, because the elastic region acts as a radial limit in the axial region covered by the adjusting washer. Thus, the elastic region is arranged radially inside the adjusting washer, and the region covered by the elastic region in the axial direction includes the region covered by the adjusting washer in the axial direction.

[0043] Here, the axial direction is parallel to the direction of the rotational axis of the shaft, and the radial direction and the circumferential direction are related to the direction of the rotational axis of the shaft.

[0044] In an advantageous embodiment, the area covered by the first retaining ring in the axial direction overlaps the area covered by the second retaining ring in the axial direction. The advantage here is that the two retaining rings are connected to each other and thus a firmly connected disk pack can be formed.

[0045] In an advantageous embodiment, the two retaining rings are arranged to be rotated 180° relative to each other. The advantage here is that only a single type of retaining ring needs to be manufactured and stored.

[0046] In an advantageous embodiment, the bearing ring is an outer ring, wherein the bearing assembly has a cover part, which has a centering collar which projects into a hole in the housing part.

[0047] The gasket set is axially arranged between the cover and the outer ring, in particular, between the centering flange of the cover and the outer ring.

[0048] In particular, at least one of the retaining rings has a radially outwardly projecting projection, which projects into an axial groove of the housing part, in particular into an axial groove of the housing part arranged on the hole. The advantage here is that the shim pack is limited in the axial direction by the cover part and is thus fixed between the outer ring and the cover part. Here, the cover part defines the axial position of the shim pack with its centering flange that projects into the hole. Since this position may vary due to manufacturing, the axial width compensation of the shim pack can be achieved by selectively adjusting the number and axial thickness of the shims, so that the outer ring of the bearing can be limited to the desired axial position.

[0049] In an advantageous embodiment, the bearing ring is an inner ring.

[0050] The gasket set is arranged axially between the shaft shoulder and the inner ring of the bearing.

[0051] In particular, at least one of the retaining rings has a radially inwardly projecting projection which projects into an axial groove of the shaft. This has the advantage that the axial position of the shaft shoulder is different and that the desired axial position of the inner ring can thus be achieved by selecting the number and axial thickness of the adjustment washers. In addition, a positive locking against rotation can be achieved simply by shaping and introducing the axial groove.

[0052] In an advantageous embodiment, the area covered by the axial groove in the axial direction includes the area covered by the shim pack in the axial direction. The advantage here is that an anti-rotation lock can be realized in a simple manner.

[0053] In an advantageous embodiment, an adhesive is arranged in or on the gasket pack. This has the advantage that additional insurance can be provided.

[0054] In an advantageous embodiment, the adjusting disk is designed as a perforated disk, in particular wherein the axial thickness of the adjusting disk is smaller than the axial thickness of the retaining ring. This has the advantage that the retaining ring reinforces the disk package and thereby also enables an interruption in the circumferential direction which bridges the respective contact surface of the respective retaining ring on the side facing away from the adjusting disk.

[0055] In an advantageous embodiment, an axially continuous hole is formed in the respective retaining ring, the hole being arranged in particular radially outside the adjusting washer.

[0056] wherein the connecting element, in particular the pin, in particular the pin passes through the hole,

[0057] The connecting element extends into the axial hole.

[0058] In particular, the holes are particularly evenly spaced apart from each other and / or are arranged at the same radial distance in the circumferential direction. Advantageously, anti-rotation locking can be achieved in a simple and cost-effective manner by means of the pin.

[0059] In an advantageous embodiment, the bearing ring is an outer ring, wherein the axial hole is arranged in the cover element.

[0060] In particular, the axial hole is arranged as a blind hole. This has the advantage that the anti-rotation locking part can be anchored in the cover part. As a result, it is not necessary to form a hole in the bearing, in particular in the outer ring. The cover part is connected to the housing part that receives the bearing by means of axially oriented connecting screws and is thus connected in a rotationally fixed manner.

[0061] In an advantageous embodiment, the bearing ring is an inner ring, wherein the axial hole is formed in the shaft, in particular in a shaft shoulder of the shaft, in particular as a blind hole. This has the advantage that the shaft shoulder has sufficient material thickness for forming the hole. This allows a very compact embodiment.

[0062] In a reducer having, in particular, the above-described bearing assembly, an important feature is that the shaft is connected to the toothed part in a rotationally fixed manner. Advantageously, the shaft is a transmission shaft, in particular an input shaft, an intermediate shaft or an output shaft. The shaft is arranged at the axial end facing the cover in a manner protected from the environment by the cover.

[0063] Further advantages are given by the dependent claims. The invention is not limited to the feature combinations of the claims. For a person skilled in the art, in particular from the objectives proposed and / or by comparison with the prior art, other reasonable combinations of the claims and / or the features of the individual claims and / or the features of the description and / or the features of the drawings are available.

[0071] As shown in the figure, a bearing for rotatably supporting a shaft 7 is received in a housing member 3. In particular, an outer ring 4 of the bearing is received in a through hole of the housing member 3, and an inner ring 6 is fitted onto the shaft 7. A rolling body 5 is arranged between the inner ring 6 and the outer ring 4.

[0072] The inner ring 6 bears against a stepped portion of the shaft 7 and is thereby axially limited relative to the shaft 7 .

[0073] The cover 2 covers the hole toward the environment and, for this purpose, rests against the housing part 3. In particular, the screws passing through the cover 2 press the cover 2 against the housing part 3 with their screw heads, and the threaded area of ​​the screws is screwed into the threaded holes of the housing part 3. The centering collar of the cover 2 projects into the hole. The outer ring 4 is axially limited by the shim set 1 arranged axially between the outer ring 4 of the bearing and the cover 2.

[0074] The axial limitation is determined by means of the axial thickness of the disk package 1 .

[0075] As shown in FIGS. 2 to 6 , the disk set 1 has shims 40 which are received on both sides in the axial direction by retaining rings 20 which can be connected to one another.

[0076] The adjusting washers 40 are designed as perforated washers and all have the same outer diameter and the same clear inner diameter. The axial thickness, in particular the wall thickness, of the adjusting washers 40 can be the same or different. Preferably, the thicknesses each have a value in the range of one tenth to five tenths of a millimeter, i.e. 0.1 mm to 0.5 mm.

[0077] As shown in FIG. 4 , a plurality of shims are arranged between the two retaining rings 20 in the axial direction, so that the outer ring is axially restricted according to the number and axial thickness of the shims 20 .

[0078] The retaining ring 40 preferably has a greater axial thickness than the adjusting washer. Thus, the retaining ring 40 is more stable and / or harder than the adjusting washer 20.

[0079] The retaining ring 40 has a smaller clear inner diameter than the adjusting shim 40 .

[0080] The retaining ring 40 has a larger outer diameter than the adjusting shim 40 .

[0081] Preferably, at a radial distance greater than the maximum radial distance of the adjustment shims 40, the retaining ring 40 has axially continuous holes 22 spaced apart from one another in the circumferential direction, through which holes the grooved pin 8 is guided, which extends into the axial bore of the cover 2 and through the holes of the two retaining rings 40 of the shim set 1. As a result, the shim set 1 is locked against rotation relative to the cover 2.

[0082] The two retaining rings 20 of the disk package 1 are designed to be structurally identical, ie, in particular, identical to one another, wherein the two retaining rings are, however, arranged in the disk package 1 rotated by 180° relative to one another.

[0083] Each retaining ring 20 has elastic regions 21 spaced apart from one another in the circumferential direction at its radially inner edge region. The respective elastic region is designed as a curved region and extends longer in the circumferential direction than in the axial direction.

[0084] The respective elastic region 21 is formed as a tongue extending in the circumferential direction and protruding slightly in the axial direction on the retaining ring 20 .

[0085] Therefore, if the second elastic region 21 of the second retaining ring 40 is pushed behind the first elastic region 21 in the circumferential direction, the first elastic region 21 of the first retaining ring 40 can be elastically displaced in the axial direction. Thus, the second elastic region 21 of the second retaining ring 20 clamps the first elastic region 21 of the first retaining ring 20 from below.

[0086] In order to improve the penetration during the described clamping from below, each elastic region 21 has an insertion bevel.

[0087] This form-fit connection caused by the relative rotation of the two retaining rings 40 can also be referred to as a bayonet connection, in particular wherein the first retaining ring 40 serves as a first bayonet connection and the second retaining ring 40 serves as a second bayonet connection.

[0088] In particular, the corresponding elastic region 21 is formed and shaped by punching and bending. In particular, the elastic region 21 is designed to be connected to the rest of the retaining ring 40, ie, is integrally and / or in one piece with it.

[0089] The adjustment washers 20 arranged between the retaining rings 40 are axially limited and closed by clamping the elastic regions 21 of the two retaining rings 40 together at the bottom. The individual adjustment washers 20 cannot bend. In addition, the adjustment washers 20 are abutted against each other without gaps, especially without interruptions in the circumferential direction.

[0090] A radial outward displacement of the adjusting disk is avoided due to the respective elastic regions 21 , which are arranged distributed over the circumference and protrude axially relative to the respective other retaining ring.

[0091] The first retaining ring 40 abuts against the outer ring of the bearing, and the second retaining ring 40 abuts against the cover 2. However, the abutting surface of the second retaining ring 40 on the cover 2 is designed to be not continuous in the circumferential direction, but interrupted, so as to facilitate the oil supply to the bearing and to dissipate the heat of the heated oil on the inner side of the cover 2, especially to dissipate the heat from the cover 2 to the environment.

[0092] Since the second retaining ring 40 has a sufficient wall thickness, it bridges the interruption and thus achieves a stable alignment of the disk package 1 and a constant axial positioning even under load.

[0093] The shim set 1 can be manufactured in a prefabricated manner. Thus, the shim set is designed to be movable, stored and transportable as a unit.

[0094] In a further embodiment according to the invention, in addition to or instead of the grooved pin 8 , a positive locking against rotation is provided, which is achieved by at least one radial projection of the retaining ring 20 which projects into a corresponding recess, in particular a groove, of the housing part 3 .

[0095] Preferably, the groove is designed as an axial groove on the inner side of the bearing bore, ie, the housing part bore which receives the bearing outer ring.

[0096] The area covered by the grooves in the radial direction includes the area covered by the shim pack 1 in the axial direction.

[0097] The radial projection can be realized, for example, by a radially protruding bulge region of the retaining ring 20 .

[0098] In further exemplary embodiments according to the invention, an adhesive is additionally or alternatively provided in and / or on the disk package 1 , in particular as an anti-rotation lock.

[0099] In further embodiments according to the invention, other connecting elements are used instead of the grooved pin 8 , for example screws, rivets, clamping sleeves or pins other than the grooved pin 8 .

[0100] In a further embodiment according to the invention, the shim set 1 is mounted on the shaft, wherein the shim set 1 is arranged axially between the inner ring of the bearing and the shaft shoulder of the shaft. Thus, the axial position of the inner ring is defined by means of the shim set 1. In order to achieve a positive locking against rotation, the groove pin 8 extends into an axial hole formed in the shaft on the shaft shoulder, and / or at least one of the two retaining rings 40 has a radially inwardly directed protrusion, in particular a radially inwardly protruding bulge area, wherein the protrusion, in particular the bulge area, extends into the axial groove of the shaft.

[0101] In a further embodiment according to the invention, the shim set 1 is equipped with only one retaining ring, so that the adjusting shim 40 rests axially between the cover 2 and the retaining ring 20, which in turn rests on the outer ring 4. Alternatively, however, the retaining ring can also rest against the cover in order to bridge the groove of the abutment surface, and the adjusting shim is received in the retaining ring 20. The outer ring 4 then rests against one of the adjusting shims. In both alternatives, pins and / or radial projections of the above-described manner can again be additionally provided for anti-rotation locking.
